OPTICAL COATING COMPOSITION |
摘要 |
Coating compositions yielding cured coatings that exhibit excellent abrasion-resistance and hardness for use on polymeric substrates such as the front side of optical lenses, in a manner that meets or exceeds the stringent requirements for such use. The compositions include a monomeric organofunctional silane, and colloidal silica present in an amount sufficient to improve abrasion resistance as compared to a composition lacking the colloidal silica.
